To all/whom it /nay concern: 7

Be it known that LEDWARD T.-BUR;RowEs, a citizen of the United States, residing at Portland, in the county of Cumberland and State of Maine, haveinvented certain new and useful Improvements in Window- Screen Construction, of which the following is a-specification.

This invention relates to window screens designed. for the purpose of excluding insects, and moreparticularly to rolling or collapsible screens of this character.

Oneobject ofthe invention isto provide, in connection with a collapsible screen of exceptionally simple construction, improved means for supporting suchscreen upon the upper sash of a window.

Another object is to provide means for securely holding the lower end of such screen in position.

A further object is to provide; an improved guard or shield for, protecting the screen from the weather.

In order that the invention may be read ily understood, referenceis had to-the ac companying drawings, forming part of this specification, and in which,

Application filed. January 18,1915. Serial No. 2,841.

and known as linette; This is flexible and substantially waterproof. Such fabric orf nettingis secured at each endto a roller,

preferably of the shape shown in Fig. 12,

,the upper roller. being designated by the reference character 10 and the lower by the reference. characten 10 Each roller is preferably provided with a longitudinal groove 11, inwhich the end ofthe netting is secured by. means of a strip or. key 12. It will be understood that the netting may be rolledupon oneor both. ofthese, rollers as may be desired' In a prior application, Serial No. 1,310, filed January 9, 1915, I have described and claimed a screen of this general character having rollers provided withgresilient means for engaging the-Wmdeww stiles in the runways 8-, butin the present invention, the rollers 10 and 10? are solid rigid pieces, preferably formed of wood. Improved means are provided for resiliently grippingthe ends ofthese rollers and for supporting'the upper roller from the sash 6., In order that the length of these rollers may beaccurately adjusted, I provide a screw 15, having a fiat head 16, the outer surface of which isv preferably, roughened,,as shown=in-Fig-. 14. The head of this screw also has a milled, edge, by means of which it-,may'be-readily'turned by the fingersv It will be understood that they screws 15 i are provided;w-ith suitable threads capable'of entering thewood ofthe. rollers, and may be screwed in or outso as to produce slight variations in the efieotive length: of such rollers. e

My improved means: for supporting the upper roller fromthe' sash-6 consists of a pairv of'brackets, such as shown in Fig; 7, and designated by the reference character 17 Each of these-brackets is of substantial inverted Lp-shape, having-a portion 18 -adapted to'be secured tosthe lower edge of the upper sash; To this-end, such portion is 7 a nail or screw 24, and with prongs struck out from the material of the bracket and adapted to be driven into the sash. The vertical portion of each bracket is roughened on its inner face, as indicated at 21, and is so bent as to be supported against the window stile only at the ends 22 and 23 thereof. That portion of the bracket, therefore, between the points 22 and 23 is spaced from the window stile and forms a resili ent support against which the end of the roller abuts. These brackets are preferably formed of very thin sheet metal of consid erablc elasticity, such as steel.

By reference to Fig. 5, it is obvious that the upper roller 10, when out to the proper length, is inserted between the two spring brackets 17 in such a manner that the ends of the roller are resiliently and frictionally engaged by such brackets and the roller thus supported. It will be understood that the bracket at one end of the roller preferably engages and bites into the bare wooden end of the rolleritself, while the bracket at the other end engages the roughened head 16 of the screw 15.

IVhile elements 10 and 10 have been referred to as rollers, it will, of course, be clear that they are not designed to turn after being placed in position. The screen material is unrolled to the desired length and then the upper roller forced or jammed into place.

The lower roller is adapted to rest upon the sill 5, and in order to hold it in position, two spring clips or brackets 25 are provided at the lower end of the runways 8, as clearly shown in Fig. 6. These clips or brackets are provided with a flat portion 26, having holes 27, by means of which the bracket may be secured to the window stile, and its lower free end is preferably roughened, as indicated at 28. It will be understood that the roller 10 is frictionally gripped between the roughened ends of these resilient clips or brackets, as shown in Fig. 6.

In some cases the edge of the blind stop 4 may be wide enough for the edge of the screen to lie against, but in many cases it will be found desirable to provide an auxiliary strip 13. This is secured to the edge of the blind stop 4, as by means of slender nails 14, as shown in Fig. 3. It will be particularly noted that this strip 13 does not come flush with the inside face of the blind stop 4, but is set out a little as indicated at 13, so that the edge of the screen and its fastening means will not interfere with the free travel of the sash in the runway 8.

If found necessary, suitable tacks or other fastening devices may be employed to hold. the edge of the screen to the strip 13. A convenient form of tack is shown in Fig. 13,

and consistsof a body 29 formed of sheet metal and having a plurality of prongs 30 struck out therefrom. At one end, the body 29 is preferably provided with a raised portion 31, which facilitates the removal of the tack, as will be obvious.

Instead of the bracket shown in Fig. 7, the form illustrated in Fig. 8 may be employed. This bracket 17 is provided intermediate the endsof its vertical portion with a transverse rib 32, thus dividing the bracket into portions 50 and y, each of which is spaced from the window stile by the rib 32 and capable of yielding. This construction ther fore provides a resilient bracket, serving to exert a frictional gripping action on the ends of the roller in very much the same manner as the bracket shown in Fig. 7. The bracket 17', shown in Fig. 9, however, may sometimes be employed and need not be resilient. Where such a non-resilient bracket, r'esting solidly against the window stiles is used, I preferably provide the end of the roller with a cushion or buffer 33, formed of soft rubber or the like, which will yield sufficiently to produce the frictional gripping action necessary to hold the roller in position. The buffer 33 may be secured to the end of the roller by means of a nail or screw 34.

It will be understood that when not in use, the screen may be wound upon one or both rollers and the two rollers held by the brackets 17, under the sash, as indicated in Fig. 5, the lower roller in this figure being shown in dotted lines. In my prior application above referred to, I have shown and claimed a shield or guard for protecting the rollers from the weather when in such stored position. In my prior construction, the shield was shown as secured to the sash by any suitable fastening means, such as nails or screws. In the present invention, I have devised improved means for holding this shield, as will be seen by reference to Figs. 4 and 5. Such means preferably consist of a number of spring clips 37, secured to the sash at intervals, as by means of nails 38.

The shield itself is designated at 34, and preferably consists of a strip of waterproofed paper, such as is commonly em ployed for building purposes. The edges of this strip may be folded back, as indicated at 35 and 36, the folded edge 36 being inserted under the clips 37. By reference to Fig. 5, it will be seen that the shield lies over the portion 18 of the brackets 17 and it will be understood that no appreciable crack exists between the roller 10 and the folded edge 36 of the shield, the clips 37 being, in practice, formed of very thin material.

It will thus be seen that the gist of the invention consists in frictionally supporting a screen roller between a pair of brackets, preferably resilient, carried by the upper sash, and it is thought that the many advantages of this simple, cheap and efficient construction will be readily appreciated without further discussion.

What I claim is:

1. The combination with a window having the usual upper sash, of a pair of brackets carried by said sash, a flexible screen, a bar to which said screen is secured and on which it is wound, and means for frictionally and non-rotatably supporting said bar between said brackets.

2. The combination with a window having the usual upper sash, of a pair of angle brackets having one arm secured to the lower edge of said sash, a flexible screen, a

bar to which said screen is secured, the extreme ends of said bar being frictionally engaged by the other arm of said brackets, and thus supported and held against rotation.

3. The combination with a window having the usual upper sash, of a pair of resilient, brackets carried by said sash and having portions adapted to engage the window frame, a bar frictionally held between said brackets, said bar being gripped by those parts of the brackets between the frame engaging portions, and a flexible screen secured to said bar.

4-. The combination with a window having the usual upper sash, of a flexible screen, a bar to which said screen is secured and on which it is wound, and a pair of brackets carried by said sash, between which brackets the ends of said bar are resiliently gripped and the bar thus held against rotation.

55. In a window screen, a piece of screen material, a bar to which said material is secured, a screw set into one end of said bar for adjusting the length thereof, and a pair of spaced supports between which said bar is frictionally carried, and against one of which the head of said screw bears.

6. In a window screen, the combination with a pair of supporting brackets, of a screen having a bar frictionally held between said brackets, and a screw set into one end of said bar for adjusting the length thereof, the head of said screw having a frictional outer surface.

7. The combination with a window, of a screen therefor, said screen comprising upper and lower bars, and flexible screen material secured to said bars, means for supporting the upper bar, and a pair of spring clips secured to the window stiles at the bottom of a sash runway, said clips serving to frictionally engage the end surfaces of the lower bar and frictionally hold such bar between them.

8. The combination with a window having the usual blind stop, and sash runways, of a pair of bars located in the upper sash runway, flexible screen material secured to said bars, and a strip against which the edge of such material is adapted to rest, said strip being secured to the blind stop and having its inner face beyond the inner face of said blind stop, whereby the sash runway is left clear and unobstructed.

9. The combination with a window hav ing the usual upper sash of a flexible screen therefor. and a bar on which it may be wound, said bar being located between the window stiles below the upper sash, and a housing carried by said sash and adapted to protect said bar from the weather, said housing being formed of a strip of prepared paper having its edges folded over on themselves.

10. The combination with a window having the usual upper sash of a flexible screen therefor, and a bar on which it may be wound, said bar being located between the window stiles below the upper sash, a housing carried by said sash and adapted to protect said bar from the Weather, said housing being formed of sheet material, and a series of clips attached to said sash, under which clips one edge of said housing is removably secured.

In testimony whereof I have aflixed my signature, in presence of two witnesses.
